Postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery and results in increased health-care utilization. This study identified new transthoracic echocardiographic predictors POAF using an index the total conduction time derived on tissue Doppler imaging (PA-TDI duration) patients undergoing off-pump coronary artery bypass grafting (OPCAB). A 88 isolated OPCAB were enrolled. They examined preoperatively echocardiography with evaluations monitored postoperatively continuous electrocardiographic telemetry for 7 days. occurred 35 (39.8%). Patients had significantly longer duration hospital stay than those without (44.9±6.2 vs. 37.3±3.3 days, P=0.04). Multivariate analysis showed that PA-TDI (odds ratio [OR], 1.11; 95% confidence interval [CI]: 1.06-1.16; P=0.0001) left volume (LAVI; OR, CI: 1.02-1.20; P=0.01) independent POAF. Moreover, was more reliable, given area under receiver operating characteristic curve 0.85 (sensitivity, 74.3%; specificity, 86.8%).PA-TDI predictor following OPCAB. Awareness risk may lead to prevention POAF, rapid response shortened stay, improved prognosis.
